An array A[1...n] contains all the integers from 0 to n except for one
number which is
missing. In this problem, we cannot access an entire integer in A with a
single operation.
The elements of A are represented in binary, and the only operation we can
use to access
them is “fetch the jth bit of A[i]”, which takes constant time. Write code
to find the
missing integer. Can you do it in O(n) time?
